LYSANDER A. ORCUTT, or ALBANY, NEW YORK.

COOKING-STOVE.

Specification of Letters PatentNo. 5,987, dated December 26, 1848'.

To all whom it may concern:

Be it known that I, LYSANDER ALORGUTT, of Albany, in the county, ofAlbany and State of New York, haveinvented certain new and usefulImprovements in Cooking- Stoves; and 1 do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification, in which- Figure 1 is a perspective view of a stoveembodying my improvements, and Fig. 2 is a. vertical longitudinalsection of the same showing the disposition of the flues, &c.

The same letters refer to corresponding parts in both figures.

The nature of my invention consists in substituting in cooking stoves anopen Frankin fire place in lieu of the usual close fire chamber; (saidopen fireplace however being so arranged as to be capable of beingconverted at pleasure into a close-fire chamber); and also in a newarrangement of flues and apertures to create a current of hot airthrough the oven, to carry off the moisture, &c., generated in the actof baking.

My stove is of the cubical form the oven a being situated immediately inthe rear of the open fire place 6, which latter extends from the bottomto the top of the stove and occupies its entire width. The top, bottom,front and back plates of the oven are situated at such distance from theadjacent outer plates of the stove, as to leave a vacuity between them,which vacuity forms the four flues c 0, d cl, 6 e, and f f extendingentirely around the oven, the latter flue communicating with the fireplace at its top. The front flue 0 c, is closed at the top with theexception of the port-ion lying under the smoke pipe g, which issituated at the center of the top of the stove and nearly over the fluec c. The before mentioned opening in the top of this flue is connectedwit-h the smoke pipe opening, by a close boxing z' 2', so that the onlyegress from the upper part of the flue, is through the boxing and smokepipe. It will be observed that the middle portion only of the front ofthe flue f f, is obstructed by the boxing z i, there being a freepassage upon each side, through which the heated current passes in itspassage from the upper part of the fire place as indicated by the arrowsin the drawing. From thence, when the oven is in use, the current passesto the rear and down the flue c e at the back ofthe stove, thencethrough d d beneath the oven to the front flue c c;

ascending which, and passing through the boxing i 2' before described,it passes to the smoke pipe.

In the back side of the boxing; 2', is a large aperture 71,, governed bya flap damper j which serves to close it when the oven is in use, asjust described. The damper j is so large,.as when thrown into theposition shown in the. drawings to entirely close the passage from thefront flue c 0 through the boxing i 2'. In this case the current ascendsfrom the fire place into the top flue f, passing through the intervalsupon each side of the boxing, and revert-ing, enters the opening it andescapes directly into the smoke pipe, as indicated by the red arrows. Alarge movable plate or door is provided by means of which the frontopening of the fireplace may be entirely closed, converting the wholeinto a close stove, fuel in this case being introduced into the fireplace by a side door, and the draft admitted by drawing back the hearthplate.

The fireplace may be used either with wood or coal, (a grate m beingintroduced in the latter case) and the whole arrangement combines allthe conveniences of an open fire place for roasting, broiling, &c., asalso the cheerfulness of an open fire, when used only for heating, withall the advantages of a close airtight cooking stove.

My second improvement regards the introduction of a current of hot airinto the oven as before mentioned.

a n is a vacuity between the two plates at the back of the fireplace. Itis closed at the top and has openings communicating with the externalair at 0, which maybe closed at pleasure by a damper 9. One or moretubes 9 form a communication from this vacuity to the oven, said tubespassing through the front flue c 0 without communicating therewith, andopening into the oven In the middle of the hinderl as indicated by thedotted arrows, through the tube 9 into the upper part of the oven,

while the steam and gases generated in baklng are carried off throughthe opening 1" by the draft created in the small flue s s, t t,

1n consequence of the communication of this latter with the more highlyrarefied-air inthe front flue 0 0, and pass eventually into the bottomof the oven, this state of things is reversed, and'it is to this latterarrangement, I intend to confine myself in my claim hereinafter recited.v. i a

What I claim as my invention and desire to secure by Letters Patent is ai The introduction of heated air from the vacuity n n between the twoplates at the back of the fireplace, into the upperspart of the oven, bymeans of a pipe or pipes which pass through the front flue c c,incombination with the exit passage 1", situated at, or 'near the bottomof the oven, and

'the small 'flues s 3 and t 6 arranged and operating as herein setforth.
